Initial alignment method and system for use in manufacturing an optical filter |
摘要 |
An alignment system finds the coordinates of a first point on a photosensitive optical fiber by scanning an ultraviolet beam across the fiber several times at successively decreasing speeds and detecting light returned from the fiber. The coordinates of a second point on the fiber are found similarly. On the basis of the coordinates of the first and second points, the alignment system automatically aligns the fiber in a direction suitable for the formation of an optical filter in the fiber.
